Yeah...to get a professional paint job on those 4 pieces, and for it to look really nice will cost around $800...or atleast that's how much the body shop I work at would probably charge. If you sand it yourself, it won't be as much. To prep it, all you need is a red scotch brite pad or 2, and just scuff them until they aren't shiny any more. That's how it's done everywhere...except Maaco...I doubt they even sand their shit. Dont' Go Maaco...please.
